Meteoric Iron. Before 1000 BC meteoric iron or occasionally small native iron deposits were worked. These sources are pure iron and can easily be turned into weapons. In Tutankhamun's tomb was found a meteoric iron dagger. Only tiny quantities of such sources are available. Bog Iron. Iron production in significant quantities began around

In a situation such as you present I believe there will be a few older folks who know stuff and how to make things fro scratch. But older folks need younger folks who have the physical strength to get the ore from the ground/mountain.
